You need to work out which disk is generating the error (you can match the gptids to the output from glabel status)

Then run smartctl -a dev/daX on whatever disk you find are those 2 marked as having bad checksums.

A handy utility that runs from the command line: https://github.com/nephri/FreeNas-DiskList

It gives you a list of all your gptid numbers and relates them back to the da / ada number and even tells you what port it is on if you have a sas backplane like I do.

I use it. Others also. Take a look at this post to see an example of the output:

where...did the 'pool' column go in system>disks?

that was just about the only reason to even go to that page...and now it's gone in both truenas and freenas? am i missing it somehow? searching for anything on it is impossible.....system or disk is in like every single google or forum search result :/
